On Friday (12 September 2025), NATO Secretary General Mark Rutte and Supreme Allied Commander Europe (SACEUR) General Alexus G. Grynkewich held a joint press conference to outline NATO’s response to the violation of Polish airspace by Russian drones two days earlier. Mr Rutte announced the launch of “Eastern Sentry,” a military activity aimed to bolster NATO’s posture along the eastern flank.
Afaik, this operation was planned before the latest drone escalations in Poland & Romania. It seems that the recent developments would amplify the response.
